Abstract
An image processing system including an imaging unit mounted on a subject vehicle, and an image analysis unit that acquires images photographed by the imaging unit. The image analysis unit acquires plural images with different exposures that the imaging unit photographed, detects light spots emitted from the other vehicles from the plural images with different exposures, and detects positions of the other vehicles. The plural images are an image photographed with a first exposure, and an image photographed with a second exposure greater than the first exposure. The image analysis unit extracts a first area containing a first color component from the image photographed with the first exposure to determine the first area to be a first three-dimensional object, and extracts a second area containing a second color component from the image photographed with the second exposure to determine the second area to be a second three-dimensional object.
